The PRINTTEC STW1320 is a heavy-duty coil cord with earth lead. It is designed to provide low-resistance ground and anti-static protection. It is constructed with a black insulated cable for maximum conductivity and flexibility. The cable is 1.8 meters long with a coiled end to reduce the risk of snagging and tangling. It is also designed to prevent electrostatic discharge (ESD) and provide a safe connection to electrical outlets.
